This thesis investigates architectural design as a sensory device that mediates the relationship between the body and the environment. I used a bridge as a site since the body is fully exposed to an open environment, vet often one is barely aware of the environment due to the linear and repetitive nature of the bridge form. My attempt is to amplify and variegate the experiences of the bridge by using environmental information itself as a material for design. In order to capture the nature of environmental information I employed computation and developed generative processes as tools for design. The possibility of this mode of design can be contested by means of digital computation through algorithmic processes which allow one to operate on relationships and attributes and implicitly evolve a final design product without preconditioning the outcome by formal biases. Thus, rather than allowing the logic of a predetermined form to dictate architectural choices, such as material and structure, the form emerges out of a computationally calibrated distribution of properties in space.

Abstract:
Thesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, June 2003.
Includes bibliographical references (leaves 39-41).
Commerce is all about the carefully managed exchange of material, money, and information. Traditionally, the connection between material and information has been tenuous, with humans acting as the intermediaries. This has made the supply chain inefficient and expensive. The Auto-lID Center has created a stronger, automatic link between inanimate objects and computers. This thesis completes the information exchange, or feedback loop, which makes commerce possible. Specifically, it identifies a framework for information exchange alongside material exchange using Savant-to-Savant communication. Messaging standards will need to support the Auto-ID Center's technology, and this thesis suggests how to augment existing and emerging communication standards to accomplish this feat. Finally, to address the issue of increasing information management, this thesis analyzes the aggregation database, an IT infrastructure component that might be of value to organizations. The outcome of this thesis is an understanding of the various issues necessary to develop a secure, efficient and robust system for tracking and automatically confirming material exchange.

Abstract:

Syftet med arbetet har varit att skapa informationsmaterial till Eskilstuna konstmuseum som är anpassat efter målgruppen. Detta önskades eftersom inget liknande material fanns sedan tidigare på konstmuseet. Målet var att besökare och potentiella besökare snabbt skulle kunna få en överblick av vad museet hade att erbjuda. Men också för att ge besökare en möjlighet att kunna få förståelse för vad som visas och hur utställningarna är uppbyggda, utan att behöva gå en guidad tur.

Detta har gjorts till större delen genom analyser och litteraturstudier, men utprovningar har också varit en stor del av arbetet.

Resultatet blev två broschyrer som togs fram enligt riktlinjer för informationsdesign, en informationsbroschyr och en broschyr om samlingen.

Abstract:

I Sverige finns idag drygt en miljon abonnenter med fast internetanslutning. En stor del utav dessa fildelar eller laddar ner upphovsrättsskyddade filer. Antipiratbyrån är en föreningen som bland annat vakar över video- och datorpelsbranchens intressen att upphovsrätten efterföljs och arbetar således mot illegal fildelning.

Syftet med uppsatsen är att granska effekterna av Antipiratbyråns arbete och finna orsaker till dessa effekter. Uppsatsen ska även ge en bakgrund till fildelningens utbredning och arbetet mot olaglig fildelning i Sverige. En trianguleringsmetod har använts för att uppfylla första delen av rapportens syfte. En kvantitativ undersökning har genomförts för att ta reda på hur fildelarnas fildelningsfrekvens har påverkats av Antipiratbyrån. För att finna orsakerna till detta har en kvalitativ undersökning genomförts, genom att undersöka fildelarnas attityder. Den andra delen av syftet har besvarats genom en kvalitativ litteraturstudie. Anledningar till att fildelningen är så utbredd är för att fildelningsprogrammen inte längre kan stängas ner lika lätt, 84% av Sveriges befolkningen använder dator minst en gång i veckan och 36% av alla internetanvändare har tillgång till bredband. Utfallet från den kvantitativa undersökningen visade att 3% helt slutat fildela, 17% fildelar mindre, 63% fildelar lika mycket och 17% fildelar mer. Dessa siffror varierar inte i någon större utsträckning mellan kön eller olika åldersgrupper. Respondenterna har delats in i grupper till den kvalitativa undersökningen, baserat på vilket av ovanstående svarsalternativ de valt.

Den kvalitativa undersökningen visade att samtliga respondenter tycker att fildelning ger en hög belöning till låg eller ingen risk. Ändå har de 20% som slutat eller dragit ner på fildelningen påverkats av risken medan de övriga 80% inte påverkats. Det visar att de som helt slutat eller dragit ner på fildelningen är mindre riskbenägna. Bland de som fildelar mer är det en övervägande del som gör det för att trotsa Antipiratbyrån. Bland svarsalternativen helt slutat fildela, fildelar mindre, fildelar lika mycket och fildelar mer har attityden högt pris påverkat en majoritet av fildelarna i alla svarsalternativ utom helt slutat fildela. Attityderna lagarna är inkorrekta, omedveten om lagarna, omedveten om skadorna och handlingarna åsamkar ingen skada har inte påverkat fildelningsfrekvensen hos fildelare inom något svarsalternativ. I och med att det är många attityder som inte påverkat fildelningsfrekvensen hos fildelare i alla svarsalternativ visar det att fildelarna har det utilitariska synsättet. De bryr sig mer om resultatet av fildelningen än hur de når upp till det.


Today there is more than one million broadband subscribers in Sweden. A large part of the subscribers share files or download copyrighted works. The Swedish Anti-piracy Bureau is an association that works against the illegal file sharing.

The purpose of this thesis is to review the effects of the work of The Swedish Anti-piracy Bureau and to find causes of these effects. The thesis will also present a background to the widespread file sharing and the work against illegal file sharing in Sweden. A triangulation method has been used to fulfill the first part of the purpose. A quantitative study has been carried out in order to research how the frequency of the file sharing has been affected by The Swedish Anti-piracy Bureau. To find the causes of this, a qualitative study has been accomplished by examining the attitudes of the file sharers. The second part of the purpose has been answered through a qualitative literature study. The reasons to why file sharing is widespread is because the file shareing software cannot be shut down as easily anymore; almost 84% of the population in Sweden use a computer at least one time per week, and 36% of all the Internet users have access to a broadband connection.

The result from the quantitative study showed that 3% had stopped file sharing, 17% are file sharing less, 63% are file sharing equally much and 17% are file sharing more. These numbers do not vary to a large extent regarding sex and different age groups. The respondents have, based on what of the above stated answer was, been divided into groups for the qualitative study.

The qualitative study showed that every respondent think that file sharing gives a high reward to a low or non-existing risk. Still, the 20% who have stopped or decreased their file sharing have been affected by the risk, while the remaining 80% have not been affected. This shows that those who have stopped or decreased their file sharing shows less risk tendency. Among those who file share more a predominant part do it in defiance of The Swedish Anti-piracy Bureau. Among the answer alternatives stopped file sharing, file sharing less, file sharing equally much and file sharing more the attitude price has affected a majority of the file sharer in all answer categories except stopped file sharing. The attitudes the laws are incorrect, unaware of the laws and the actions does not hurt anyone have not affected the frequency of the file sharing within any answer category. The fact that there are many attitudes that have not affected the frequency of the file sharing in any answer category, shows that the file sharers have the utilitarian view. They care more about the result of the file sharing than how it is achieved.

Abstract:
The purpose of this bachelor’s thesis is to explore the information practices present in hobby genealogy. The thesis uses a qualitative content analysis to analyse two popular Swedish genealogy magazines published between 2016 and 2019. The study investigates the information sources, objects, competences and emotions that the practice is built on. Our theoretical framework is centred around Reckwitz’ ideas of practice theory (2002), and the practice theory model introduced by Shove, Pantzar, and Watson (2012). The study finds that the information practices within hobby genealogy are heterogenous and extensive, and that information is a central part of the practice. The study also finds that emotions and motivations are important parts of understanding how the practice is maintained.

Abstract:

Denna uppsats dokumenterar en fallstudie som gjordes hösten 2006 vid Linde Material Handling i Örebro. Företaget var på väg att expandera och planerade att utöka användningen av IT i verksamheten. I samband med detta gavs undertecknade i uppdrag att utforma en informationssäkerhetspolicy för verksamheten. I en litteraturstudie kunde det konstateras att det inte fanns några enklare riktlinjer för att utforma sådana policies, varmed syftet blev att göra detta. Genom en fallstudie på företaget där vi utformade en IS-policy för deras verksamhet, och även gjorde intervjuer med ledning och dokumentationsanalyser, utrönas vilka problem som kan uppstå och vilka överväganden som bör göras för att utforma en lyckad policy. Riktlinjerna kan användas av företag som känner igen sig i fallbeskrivningen. Vi har i arbetet avgränsat oss från att studera hur en policy ska införas eller utvärderas.

De riktlinjer vi utformade kan sammanfattas som följande:

* Utforma minimalistiskt

Policyn bör vara enkel, de föreskrifter och sidor som finns bör vara få till antalet och endast omfatta det absolut viktigaste.

* Tillgodose användaracceptans

Policyns innehåll ska inte uppfattas som kränkande eller alltför omständligt av de anställda.

* Formulera och ordna mål

Det är viktigt att se till att de säkerhetsmål som finns i verksamheten hjälper till att uppfylla de mer generella organisatoriska målen.

* Förankra i beslutande organ

Säkerhetsarbetet bör vara förankrat i ledningen.

* Uppdelning i delpolicies

Det kan vara aktuellt med olika delpolicies för olika delar av verksamheten

om dessa skiljer sig märkbart åt.

Abstract:
As time goes on, the demand for higher resolution and more visually rich images only increases. Unfortunately, creating these more realistic computer graphics is pushing our computational resources to their limits. In realistic rendering, one of the common ways 3D objects are represented is as volumetric elements called voxels. Traditionally, voxel data structures are known for their high memory requirements. One of the standard ways these requirements are minimized is by storing the voxels in a sparse voxel octree (SVO). Very recently, a method called High Resolution Sparse Voxel DAGs was presented that can store binary voxel data orders of magnitudes more efficiently than SVOs. This memory efficiency is achieved by converting the tree into a directed acyclic graph (DAG). The method was also shown to have competitive rendering performance to recent GPU ray tracers. Unfortunately, it does not support storing collections of rendering attributes, commonly called materials. These represent a given object's reflectance properties, and are necessary for calculating its perceived color. We present a method for connecting material information to High Resolution Sparse Voxel DAGs for mid-level scenes, with multiple meshes, and several different materials. This is achieved using an extended Sparse Voxel DAG, called a Moxel DAG, and an external data structure for holding the material information, we call a Moxel Table. Our method is much more memory efficient than traditional SVOs, and only increases in efficiency in comparison when at higher resolutions. Because it stores the equivalent information as SVOs, it achieves the exact same visual quality at the same resolutions.

Full text
Abstract:
Remanufacturing is an environmentally sound material recovery option which is essential to compete for sustainable manufacturing. The aim with remanufacturing at a majority of companies is to prolong physical product performance by delivering the same or betterthan-original product quality. In general, remanufacturing is an industrial process that brings used products back to useful life by requiring less effort than is demanded by the initial production process. Consequently, from a product life-cycle perspective, remanufacturing generates great product value. Remanufacturers lag behind manufacturers since they often face complex and unpredictable material and information flows. Based on a review of remanufacturing research, remanufacturing challenges in material and information flows can be classified into three groups: insufficient product quality, long and unstable process lead times, and an unpredictable level of inventory. While some remanufacturing researchers state that manufacturing and remanufacturing are significantly different, they have more in common than many other processes operations. Therefore, to sustain competitive remanufacturing, companies investigate an opportunity for improvement through the employment of lean production that generates significant benefits for manufacturers. In order to investigate the potential to address remanufacturing challenges by lean production, a Minimum time for material and information flow analysis (MiniMifa) method was developed. This method originates from the value stream mapping (VSM) method, broadly practiced to bring lean to manufacturing companies. The focus of MiniMifa was to collect empirical data on the identified groups of remanufacturing challenges from the remanufacturing perspective, and to provide a basis for the development of improvements originating from lean principles. Lean production was selected for this research due to its system perspective on material and information flows. Among the defined lean principles in remanufacturing, a pull principle was investigated at the case companies. The suggested principle demonstrated a reduction in lead time, followed by improvements in inventory level and product quality. However, in order to become lean, remanufacturers have to overcome three levels of lean remanufacturing challenges: external and internal challenges as well as lean wastes. Finally, this research reduces the gap between academia and industry by contributing with a possible solution to the identified remanufacturing challenges in material and information flows.

Abstract:
Group IV-based nanowires are excellent designed thermoelectric materials for high temperature applications. Ni silicide (germanide) has been widely used to reduce the contact resistance for group IV nanowires. In this work, the interaction of Ni with relaxed, compressive and tensile strained GeSn was investigated. The layers were epitaxially grown by chemical vapor deposition in temperature range 290-350 °C and the phase transformation of germanides was studied for three different rapid thermal annealing (RTA) temperatures of 350, 450, and 550 °C. The germanide layers were characterized using scanning electron microscopy, high resolution X-ray diffraction, and four point resistivity measurements. The results showed that NiGeSn phase with lowest resistivity is formed at 450 °C annealing and was stable up to 550 °C. The thermal stability of NiGeSn is dependent on the type, amount of the strain and the Sn content. The thickness of germanide layer for a certain RTA treatment was dependent on strain.

Abstract:
This thesis is intended to help eliminate misconceptions and missing information over the realm of smart materials, by offering a newly structured &lsquo
Information Hierarchy for Smart Materials Communication for Industrial / Product Design&rsquo
. Industrial and product designers are invited to use the findings of the thesis to assist in developing a common smart materials language and culture, enriched by details, technicalities, opportunities, and creative and innovative material attributes. The study commences with the creation of a concise and compact reservoir of technical knowledge on smart materials and critically contrasts two established systems of classification for smart materials. Then, the subject of materials information appropriate to industrial design is discussed, highlighting channels through which smart materials information may be communicated at an optimum level so as to be amenable to exploitation by industrial designers. A sectoral analysis of smart materials use follows, including the presentation of factors that may hinder their more extensive exploitation in major industrial sectors. v The thesis concludes that smart materials have potential to initiate a breakthrough in the materials universe, and that industrial designers have a role in promoting smart materials knowledge, the capabilities of smart materials, and their innovation possibilities. It is recomended that since smart materials are a new generation of materials quite different from the conventional, they be promoted carefully through the proposed Information Hierarchy.

Production systems are characterized by complex interactions between elements, both human and mechanical, with the goal to accomplish certain high-level manufacturing objectives. In order to ensure that the decisions made and the actions taken during the design and implementation of production systems are aligned with all of the objectives, a structured approach must be followed. In developing this structured approach, the axiomatic design methodology is applied, which provides the means for creating a hierarchy of system design objectives (what to do) and solutions (how to do it). From this conceptual design process, a Production System Design and Implementation (PSDI) Path is presented here. The PSDI Path guides the design through a series of steps in creating a successful physical manufacturing system environment in terms of the original high-level objectives. Defining the material and information flow in the system is a critical part of the PSDI path. Based on the steps in the PSDI Path and the design hierarchy, a procedure for constructing the material and information flow in the production system is developed. To aid in the design of material and information flow in the manufacturing system, a manufacturing system modeling environment is developed as the tool for visualizing and communicating the flow in the manufacturing system design.

Full text
Abstract:
Drones are a rapidly evolving technology with potential for different surveying and measurement purposes. With various embedded sensors, drones can provide data from their surroundings with a capability to easily reach places that can otherwise be difficult to measure. The ability to perform tasks while flying in the air and being able to do them both quickly and inexpensively is what separates the drones from more traditional measurement methods. It is also what makes the use of drones interesting in industrial environments where there is a need to have more accurate and timely measurement systems to provide information about material use and management. The objective of this thesis was to research if a drone based measurement system for outdoor material fields in industrial environment is a feasible concept. In this thesis, a drone based measurement system is considered a system, which uses a drone to collect the measurement data by taking photographs and which produces the measurements through measurable 3D models based on the photographs and GPS location data. This research was conducted with design science research methodology. The system’s feasibility was studied by implementing the system as a pilot project in an industrial environment. Prior research related to the use of drones in similar applications was analysed through a structured literature review, from which recommendations for a good system design could be derived. The system was built by applying the local needs to the system alongside with the theoretical recommendations. The completed system was evaluated by comparing the system’s performance against traditional measurement methods and by comparing the system against the requirements that it was designed with. From the results of the evaluation, the feasibility of the system could be assessed and recommendations for improving and developing the system in the future described. The research showed that a drone based measurement system for outdoor material fields is a feasible and practically working concept. The system can produce very accurate and timely results, being capable of replacing more traditional measurement methods. The system is limited by being dependent on good weather conditions and by having lack of automation in some parts of its workflow. The research as a whole was limited by its approach of pilot testing, which could make some of the results not generalizable
Dronet eli miehittämättömät ilma-alukset ovat nopeasti kehittyvä teknologia, jossa on potentiaalia erilaisiin kartoitus- ja mittaustehtäviin. Moninaisten sulautettujen sensorien avulla dronet voivat tuottaa erilaista dataa ympäristöstään, pystyen helposti yltämään paikkoihin, joita olisi muutoin vaikea mitata. Kyky suorittaa tehtäviä ilmasta käsin, sekä niiden suorittaminen nopeasti ja edullisesti on ominaisuus, joka erottaa dronet muista perinteisemmistä mittausmenetelmistä. Se myös tekee dronejen käytöstä mielenkiintoista teollisissa ympäristöissä, joissa on tarvetta entistä tarkemmille ja oikea-aikaisemmille materiaalien käytöstä ja hallinnasta tietoa tuottaville mittausjärjestelmille. Tämän pro gradu -tutkielman tavoitteena oli tutkia, onko ulkona sijaitsevia materiaalikenttiä teollisessa ympäristössä mittaava drone-pohjainen mittausjärjestelmä toteuttamiskelpoinen konsepti. Tässä tutkielmassa drone-pohjaisella mittausjärjestelmällä tarkoitetaan järjestelmää, joka käyttää dronea keräämään mittausdataa valokuvia ottamalla ja joka tuottaa mittauksia 3D-malleista, jotka pohjautuvat näihin otettuihin kuviin ja GPS-paikkatietoon. Tämä tutkimus toteutettiin design science research -metodologialla. Järjestelmän toteuttamiskelpoisuutta tutkittiin toteuttamalla järjestelmä pilottiprojektina teollisessa ympäristössä. Aiempaa dronejen käyttöön liittyvää tutkimusta vastaavissa sovelluksissa analysoitiin strukturoidun kirjallisuuskatsauksen kautta. Sen avulla voitiin johtaa suosituksia hyviä järjestelmänsuunnitteluperiaatteita varten. Järjestelmä rakennettiin soveltamalla järjestelmään paikallisia tarpeita teoreettisten suositusten rinnalla. Valmista järjestelmää arvioitiin vertaamalla järjestelmän suorituskykyä perinteisiä mittausmenetelmiä ja järjestelmän suunnitteluvaiheessa käytettyjä vaatimuksia vasten. Arvioinnin tulosten perusteella järjestelmän käyttökelpoisuutta voitiin tarkastella, sekä antaa ehdotuksia järjestelmän parantamiseen ja kehittämiseen tulevaisuudessa. Tutkimus osoitti, että ulkona sijaitsevia materiaalikenttiä teollisessa ympäristössä mittaava drone-pohjainen mittausjärjestelmä on toteuttamiskelpoinen ja käytännössä toimiva konsepti. Järjestelmä voi tuottaa hyvin tarkkoja ja oikea-aikaisia tuloksia, ollen kykenevä korvaamaan perinteisempiä mittausmetodeja.

Abstract:
AbstractBackground: In an applied engineering field like requirements engineering, the final goal of the research is its adoption by industry. For technology transfer to be possible practitioners need strong evidence for a technology’s applicability and possible benefits. Therefore research on a technology should be done in a realistic setting so that practitioners can use the results to build a strong case for its adoption. Quality requirements are constraints placed on the software. Empirical results show challenges in handling quality requirements, e.g. include late discovery of quality requirements. In addition, we lack technologies that can be used to incorporate them into the final software. Functional and quality requirements differ in nature; treatment given to functional requirements will not always be applicable for quality requirements. Therefore practitioners need decision support material based on empirical evidence to incorporate the suggested technologies.Objective: The purpose of the thesis is to identify technologies for quality requirements that have been empirically evaluated. Methods in relation to elicitation, specification, metrics (or measurement) and testing will be identified with the aim of providing decision support material to practitioners for incorporating quality requirements in the software. To find possible future directions of requirements engineering research, the current state of technology adoption for quality requirements will be identified. Method: The presented research is explorative and investigative in nature. A systematic literature review method was employed to identify potential technologies for adoption. An empirical study was conducted with three participants from three companies to get an insight into the state of technology adoption. Results: The systematic literature review includes 46 papers published between 2000 and 2010. All in all only four of the 46 papers offer high realism and support for technology adoption, i.e. presenting evaluations in a realistic setting, with practitioners using real world industrial applications. Another three papers were found to have potential in terms of furthering technology transfer. A general finding common for many of the papers reviewed is a lack of scientific rigour which affects the credibility of the results. Among the participants in the three companies interviewed, none of the methods presented were used. Conclusions: Technology transfer support for quality requirements technologies is challenged by low strength of evidence. Evaluations of technologies lack descriptions of evaluation design - description of how evaluations have been performed - and validity. There is a need for more and better empirical evaluations of technologies to handle quality requirements. The results of industrial interviews shows the need for more empirical investigations, for example surveys, to identify current industrial practices and technologies able to handle or incorporate quality requirements in projects successfully.

Abstract:
I dagens samhälle finns det ett lägre intresse och en lägre motivationsnivå hos elever i 6:an och 7:an när det kommer till de naturvetenskapliga ämnena. Tidigare forskning beskriver att elever saknar en djupare förståelse och förmåga till problemlösning i ämnet naturvetenskap.  En potentiell strategi för att öka motivationen för elever i naturvetenskapliga ämnen är med hjälp av digitalt material. Tidigare forskning har visat att utbildningsvideo och spelifiering kan användas som ett effektivt och integrerat verktyg för att öka elevers motivation inom naturvetenskapen. Syftet med detta examensarbete är att undersöka hur olika typer av digitalt material kan kombineras för att potentiellt öka elevers motivation i årskurs 6 och 7 för innehåll i fysikämnet.  För genomförandet av studien har metoden konceptdriven designforskning använts. Metoden är skapad av Wiberg & Stolterman (2010). Konceptdriven designforskning består av sju olika steg som följs för att komma fram till ett designkoncept.  Målet med examensarbetet är att designa ett koncept i enlighet med syftet som utvärderas med elever. Resultatet visar att det finns en positiv attityd bland elever i årskurs 6 och 7 till konceptet i examensarbetet. Resultatet av enkäten visade att eleverna ville använda sig mer av spelegenskaper i konceptet. Slutsatsen i detta examensarbete är att utifrån fyra olika steg (inbjudan, lärande och utveckling, test av kunskap samt resultat) där spelegenskaper och sociala komponenter tillämpas (i form av poäng, märken och topplista, lagarbete och digitala egenskaper som chattfunktion) i en spelifierad kontext kan potentiellt ha en positiv påverkan på elevers motivation. I framtida forskning behövs tas upp mer kring lärarnas perspektiv då det hade varit ytterligare en intressant synvinkel att kunna ta hänsyn till.

Abstract:

Organisations must change in order to be able to follow the expansion in the world and be competitive along with other organisations at the global market. To successfully efficient the organisations reduce their purchasing costs for material and products. One way to reduce the purchasing costs is to centralise all purchases in an organisation. When a big organisation does that, they use, among other things, the economies of scale. (Personal communication,Department Manager, 2005-06-17 and Senior adviser, IMS ITP, 2005-08-15)

While studying Information Logistics, 140 p, at the Centrum för Informationslogistik in Ljungby, has IKEA IT been our co-operating company. When we talked with our Department Manager during our internship, she describes co-operation problems between the units when they purchase IT-related indirect material. Indirect material is products that support the daily work within the organisation.

Since IKEA recently started a central purchasing function for indirect material our assignment was to see how IKEA could be more efficient when purchasing IT-related indirect material. Different units at IKEA are involved during central purchases of IT-related indirect material. The fact that many conflicts arise when different units are to co-operate is well known (Gadde & Håkansson, 1998). We found this very interesting and therefore our chose of subject.

The co-operation conflicts that have arose during our investigation shows clear signals in the theory about why they arise. According to Danermark (2000) it is more a rule than an exception that it anticipates a competition. Different occupational groups have different prestige and power, the bigger the difference is the bigger is the probability that a problem regarding co-operation arise.

One difficulty with centralized purchases is to get the different units at the organisation to co-operate. Co-operation problems could be caused by many factors for example did the different units use different terminologies and could therefore be misunderstood.(Gadde & Håkansson, 1998)

Unique for IKEA’s organisation is that all different units work against the same business concept, goal and vision (Personal communication, Senior adviser, 2005-08-15). As long as the involved units are independent and do not have identical purposes will there always be conflicts (Gadde & Håkansson, 1998). Heide, Johansson and Simonsson (2005) considers that the visions are build up on different goals. These goals are in its parts build up on a number of strategies.

All IKEA-units struggle towards the same vision and goal, but the different units use different strategies to reach the goals. This different strategy creates conflicts when the different IKEA-units should co-operate.

To make the most optimized purchase for IKEA should the purchasing department handle the contacts with the suppliers (Personal communication, Purchase Process Manager, 2005-08-27). That generates a conflict when the other involved units also want to make the first contact (Personal communication, Process Owner, 2005-09-07 and Project Manager 2005-09-23). One problem is that the purchasing department today have a lack of resources and do not have time to handle all purchases and delegate some purchases to the other involved units. This gives a double message about how IKEA want the purchasing process to work.


Organisationer har blivit tvingade att effektivisera sina verksamheter, för att vara konkurrenskraftiga på marknaden. För att lyckas med detta behöver organisationen sänka kostnaderna, på material och produkter som organisationen köper in. Ett sätt att effektivisera och sänka inköpskostnaden är att centralisera inköpen. När en stor organisation gör detta utnyttjar de bland annat skalfördelarna. (Personlig kommunikation, Department Manager, 2005-06-17 och Senior adviser, IMS ITP, 2005-08-15)

Vi har under våran utbildning, Informationslogistik 140p, haft IKEA IT som fadderföretag. Efter att vi genomfört en 20 veckors praktik på IKEA IT beslutade vi tillsammans med våran dåvarande chef att vi skulle skriva våran C-uppsats om hur IKEA kan genom bättre samverkan och kommunikation effektivisera sina inköp av indirekt material. IKEA: s centraliserade inköpsavdelning är nyuppstartad och det finns ännu ingen inarbetad arbetsrutin hur ett inköp skall gå till.

Då IKEA nyligen startat upp sin centrala inköpsenhet för indirekt material, blev vår uppgift att se till hur IKEA kan bli mer ffektiva när de skall köpa in IT-relaterat indirekt material. Olika enheter inom IKEA är involverade under inköpsprocessen. Att det uppstår konflikter när olika enheter skall samarbeta är väl känt sedan innan (Gadde & Håkansson, 1998). Vi fann detta intressant och därav vårt val av ämne.

Enligt Danermark (2000) är det snarare en regel än ett undan tag att det förekommer konkurrens inom en organisation. Olika yrkesgrupper har olika prestige och makt, ju större dessa skillnader är desto större är sannolikheten att problem med samverkan uppstår. Innan inköpsavdelningen för indirekt material startades hanterade de olika enheterna själva sina inköp. Detta medförde att det förekom flera leverantörsrelationer från flera olika enheter.

En av svårigheterna med centraliserade inköp, är att få organisationens olika enheter att samverka. Samverkningsproblem kan bero på många faktorer, exempelvis att de enheterna använder sig av olika terminologier och därför missuppfattar varandra. (Gadde & Håkansson,1998)

Unikt för IKEA organisationen är att alla dess enheter arbetar mot ett och samma mål (Personlig kommunikation, Senior adviser, 2005-08-15). Så länge de involverade parterna är självständiga och inte har identiska målsättningar, kommer det alltid att finnas konflikter (Gadde & Håkansson, 1998). Heide, Johansson och Simonsson (2005) anser att visionen byggs upp av olika mål. Dessa mål bygger i sin tur på ett antal strategier. Alla enheter inom IKEA strävar efter samma vision och mål, men de olika enheterna använder olika strategier för att uppnå dessa mål. Detta leder också till konflikter då de olika enheterna inte är ense om vilka inköp som skall prioriteras.

IKEA vill att den första leverantörskontakten skall tas av inköpsavdelningen, detta för att inköp och förhandlingsprocessen skall bli så optimal som möjligt för IKEA organisationen

(Personlig kommunikation, Purchase Process Manager, 2005-08-27). De andra involverade enheterna motsäger sig detta då de anser att de behöver kontakta leverantören av olika anledningar innan en inköpsförhandling påbörjas (Personlig kommunikation, Process Owner, 2005-09-07 och Project Manager 2005-09-23). Ett problem är att inköpsavdelningen idag har en resursbrist i form av tid, därav överlåter de vissa inköp till de andra enheterna. Detta leder till ett dubbelt budskap om hur inköpsprocessen skall gå till.

Abstract:
The increasing popularity of drones has made it convenient to capture a large number of images of a property, which can then be used to build a 3D model. The conditions of buildings can be analyzed to plan renovations. This creates an interest for automatically identifying building materials, a task well suited for machine learning. With access to drone imagery of buildings as well as depth maps and normal maps, we created a dataset for semantic segmentation. Two different convolutional neural networks were trained and evaluated, to see how well they perform material segmentation. DeepLabv3+, which uses RGB data, was compared to Depth-Aware CNN, which uses RGB-D data. Our experiments showed that DeepLabv3+ achieved higher mean intersection over union. To investigate if the information in the depth maps and normal maps could give a performance boost, we conducted experiments with an encoding we call HMN - horizontal disparity, magnitude of normal with ground, normal parallel with gravity. This three channel encoding was used to jointly train two CNNs, one with RGB and one with HMN, and then sum their predictions. This led to improved results for both DeepLabv3+ and Depth-Aware CNN.
Den ökade populariteten av drönare har gjort det smidigt att ta ett stort antal bilder av en fastighet, och sedan skapa en 3D-modell. Skicket hos en byggnad kan enkelt analyseras och renoveringar planeras. Det är då av intresse att automatiskt kunna identifiera byggnadsmaterial, en uppgift som lämpar sig väl för maskininlärning.  Med tillgång till såväl drönarbilder av byggnader som djupkartor och normalkartor har vi skapat ett dataset för semantisk segmentering. Två olika faltande neuronnät har tränats och utvärderats för att se hur väl de fungerar för materialigenkänning. DeepLabv3+ som använder sig av RGB-data har jämförts med Depth-Aware CNN som använder RGB-D-data och våra experiment visar att DeepLabv3+ får högre mean intersection over union. För att undersöka om resultaten kan förbättras med hjälp av datat i djupkartor och normalkartor har vi kodat samman informationen till vad vi valt att benämna HMN - horisontell disparitet, magnitud av normalen parallell med marken, normal i gravitationsriktningen. Denna trekanalsinput kan användas för att träna ett extra CNN samtidigt som man tränar med RGB-bilder, och sedan summera båda predikteringarna. Våra experiment visar att detta leder till bättre segmenteringar för både DeepLabv3+ och Depth-Aware CNN.

This thesis is based on the author's seven-month internship based in the gears machining module of the Saturn Powertrain, Transmission Manufacturing plant. This module has four primary functional areas with buffers between each. Variable setup times, complex part flow paths, and unpredictable equipment downtime have complicated gear production since its inception in 1990. Scheduling and material flow related issues were a large source of the relativity poor performance in gears machining as it was a leading cause of downtime in the Powertrain plant, which often translated to downtime to the powertrain customer, general assembly. This project aimed to eliminate scheduling deficiencies by implementing material and information flow improvements and beginning setup time reduction. The material and information flow improvements involved a CONWIP-like (CONstant WIP) approach to inventory control. As part of the plant's kaizen process, the setup time reduction activities were intended to begin run size reductions as an enabler for future material and information flow simplification and better achievement of the manufacturing system's objectives. As outlined herein, once run size reductions are achieved, the next step for this facility should be toward a simpler system using kanban with standard-work-in-process. The work of this project resulted in significant improvements, as measured by the facility. In addition, the project provided invaluable lessons for the author which were both technical and people/leadership related.

In a universe made of bits where everything is continuously computing and nature itself is processing information everyday, what is it that our materials compute? Specifically, what are the bits of information registered within timber? More importantly, in this universe made of bits how do we design using this information and how do we imagine new buildings? This thesis explores the use of wood as a natural material in the design and construction of complex geometrical timber structures by capturing the natural curvature found in timber into digital data and building a framework for surface timber mapping as a design method. Key results include a detailed framework for translation, method for timber mapping and a prototype utilizing this method. Future steps include growth of timber structures and the use of living material in combination with typical timber construction methods for the design and construction of future buildings.

Dredging of the ports and waterways in the United States has implications for the economy and military preparedness and is hampered by a lack of disposal areas. Current dredged material disposal site selection methodologies have several limitations, such as a lack of early public involvement in the decision making process, inadequate documentation of the assumptions entering into decisions, lack of a holistic view, and inadequate consensus building among stakeholders. The use of an interactive Geographic Information System (GIS) approach to site dredged material disposal areas is seen as a way of updating and improving current site selection methodologies. There were three specific goals of this project: 1. To develop a management approach to improve the identification and selection of dredged material disposal sites; 2. To use GIS technology as a tool to facilitate the implementation and use of that approach; and 3. To evaluate the use of GIS technology and the new approach in siting dredged disposal areas. Any useful site selection methodology must acknowledge that site selection is an inherently political process based on interpretations and perceptions of the underlying science. A two part process for evaluating, ranking, and weighting data was adopted as an effective management methodology. This process allows for public involvement built upon good science and scientific interpretation of data. The development of an interactive GIS provides the tools needed to implement this methodology. The use of visual analysis, a holistic approach, and better documentation of the assumptions inherent in any decision contribute to adaptive management of disposal areas. In addition, the interactive capability of the GIS tool allows 'what if' scenarios to be examined and allows users to immediately understand the various factors affecting disposal site location and to examine the tradeoffs inherent in any siting decision. Feedback from public demonstrations of the proposed methodology confirms that this approach to siting disposal areas is an improvement over current methods. Because it aids consensus building and fosters an adaptive management approach, this methodology has the potential to site disposal areas with less time, cost, and opposition, resulting in a better selection.

Abstract:
Lithography is the most crucial step in the semiconductor microfabrication workflow. Continuous features size shrinking co-occurs with the reduction of the exposure wavelength: a move from 193 nm light to extreme ultra-violet (EUV) at 13.5 nm is performed. The change poses a vast number of challenges that have been overcome in the past years. Among the others, the protection of the reticle front side from defects is crucial. Shielding can be achieved by means of EUV pellicles: large area (~150 cm2), freestanding, ultra-thin (~50 nm) membranes that prevent particles from landing on the reticle surface. Defects fall on the pellicle membrane, which is out-of-focus with respect to the reticle. During operation, the pellicle has to endure mechanical movements (>100 m/s2) and withstand the EUV scanner environment. With increasing source power (resulting in temperatures >500 ºC) structural and chemical integrity must be guaranteed. With multiple semiconductor manufacturers introducing EUV in HVM, an urgent need for a mass volume production-ready pellicle solution is present.In this thesis project, new generation pellicle materials are exposed to EUV light and gas atmosphere at BESSY II synchrotron beamline. The purpose is to investigate the performances of the new membrane samples in terms of the HVM production specifications. Two sets of 10x10 mm2 samples Type (A – B) with different core thickness are tested. Samples are characterized by using the following techniques: EUV transmittance and reflectance measurements, RBS, XPS, and FTIR. After exposure, all the samples undergo degradation. The main root causes are the atmosphere environment and the temperature. On the other hand, EUV light itself plays a marginal role in the process. The material etching mechanism must be further investigated through additional pellicle tests. This is a necessary step to make towards the high-volume manufacturing standards required for mass production.
Litografi är det mest avgörande steget i arbets flödet för halvledar mikrotillverkning. Kontinuerliga funktioner storlek krympande co-sker med minskning av exponeringen våglängd: en över gången från 193 nm ljus till extrem ultraviolett (EUV) vid 13.5 nm utförs. Förändringen innebär ett stort antal utmaningar som har övervunnits under de senaste åren. Bland de andra, är skyddet av rikt medel fram sidan från defekter avgörande. Avskärmning kan åstadkommas med hjälp av EUV-pellicles: stort område (~ 150 cm2), fristående, ultratunna (~ 50 nm) membran som hindrar partiklar från att landa på rikt medlet ytan. Defekter faller på denna tunna membranet, som är out-of-fokus med avseende på rikt medlet. Under drift har denna tunna att uthärda mekaniska rörelser (> 100 m/s2) och motstå EUV skanner miljö. Med ökande käll effekt (vilket resulterar i temperaturer > 500 º C) måste strukturell och kemisk integritet garanteras. Med flera halvledar tillverkare införa EUV i HVM, ett brådskande behov av en massa volym produktions klara denna tunna lösning är närvarande.I detta arbete, exponeras nya generationens denna tunna material för EUV ljus-och gasatmosfär på BESSY II Synchrotron beamline. Syftet är att undersöka prestandan hos de nya membranproverna i form av HVM-produktionsspecifikationer. Två uppsättningar av 10x10 mm2 prover typ (A – B) med olika kärna tjocklek testas. Proverna kännetecknas av att använda följande tekniker: EUV-transmission och reflektansmätningar, RBS, XPS och FTIR. Efter exponering genomgår alla prover nedbrytning. De viktigaste bakomliggande orsakerna är atmosfären miljö och temperaturen. Å andra sidan spelar EUV-ljuset självt en marginell roll i processen. Materialetsnings mekanismen måste undersökas ytterligare genom ytterligare denna tunna-tester. Detta är ett nödvändigt steg för att göra mot de höga volymer tillverknings standarder som krävs för Mass produktion.

Abstract:
Cybersecurity classes focus on building practical skills alongside the development of the open mindset that is essential to tackle the dynamic cybersecurity landscape. Unfortunately, traditional lecture-style teaching is insufficient for this task. Peer instruction is a non-traditional, active learning approach that has proven to be effective in computer science courses. The challenge in adopting peer instruction is the development of conceptual questions. This thesis presents a methodology for developing peer instruction questions for cybersecurity courses, consisting of four stages: concept identification, concept trigger, question presentation, and development. The thesis analyzes 279 questions developed over two years for three cybersecurity courses: introduction to computer security, network penetration testing, and introduction to computer forensics. Additionally, it discusses examples of peer instruction questions in terms of the methodology. Finally, it summarizes the usage of a workshop for testing a selection of peer instruction questions as well as gathering data outside of normal courses.

Abstract:
The aim of this master thesis is to examine discourses and practices in the handling of materials from the ex-treme right in the Swedish national collection at Kungliga biblioteket (the Swedish national library). Questions posed in this study concern what practices have been used in the handling of the material, the discourse sur-rounding the material and its relation to power structures. The source documents in this study come from the library’s archive records between the years 2000 and 2010. As a complement, the study also uses correspond-ence with librarians active during the time period as well as an interview with an expert on the Swedish extreme right. This study uses Foucauldian discourse analysis as a method and searches for discursive patterns and power structures in the source documents. The essay sees a complex progression in how materials from the extreme right have been handled throughout the time period 2000-2010. In summary, the researched material contains two discursive patterns. Although on opposite terms, they can both be linked to the restrictions of the material. During the time period, a separate collection was set up for extremist material, a collection which is now taken apart. This study argues that “extremism” is a relative term by definition and therefor unsuitable for labelling any material in the long run. This study is a two-year master‘s thesis in Library and Information Science at Uppsala University.

Title: Mapping of material and information flows of Getinge Disinfection AB and ABC analysis of SSC warehouse

Background: Background provides the information about current situation of the material and information flows between GDs internal warehouse and rented one (SSC). Under the material flow theory, warehouse functions like: movement, storage, and information transfer are presented.  Mapping of all processes by flowchart provides visual picture of the all activities. By analysing warehousing functions of GD, we can identify treatement areas and suggest ways of improvement. When it comes to the categorization of the SKUs in rented GDs warehouse (SSC), we used ABC analysis and ABC/ XYZ classification and classified SKUs based on criteria: production line demand frequency and sales volume of each SKU, Locating the SKUs in the right place could help the GD to manage space utilization in a proper manner.  It will create possibility to cut spending on extra storage space, and transportation. On the other hand GD’s business can operate without interruptions in the production line.

Effective warehouse management involves a through understanding of the functions of warehousing. Firms may choose to perform these functions utilising public or private warehouse facilities. Each option has advantages as well as disadvantages, which must be understood so that warehousing decisions are made. Warehousing decisions also depends on financial and service aspects of warehousing decisions. In the last part of this paper, we have discussed it using different financial and operating criteria.

 

 

 

Research questions:

 

RQ1: How can the material and information flows between GDs internal warehouse and rented one (SSC) be mapped by flowchart and providing suggestions for identified treatment areas?

RQ2: Which SKUs should GD store in internal warehouse and which in rented warehouse (SSC) by using ABC analysis on the basis of production line demand frequency and sales volume of SKUs?

RQ3: What can be recommended for the future of GD; to build a new tent outside of the plant or to continue to rent SSC warehouse?

Objectives of the study:

Map the material and information flows between GDs internal warehouse and rented one (SSC) with the help of flowchart and identification of treatment areas in all those processes, and also providing of recommendations for the future improvements. We also determined the location of GD SKUs according to the picking frequency of its production line demand and sales volume of SKUs in rented GDs warehouse (SSC) based on ABC/ XYZ classification.

Discuss costs, benefits and risks relating to GDs internal warehouse and rented one (SSC) based on financial and operating criteria; and recommend to GD a suitable one.

Methodology:

Our thesis was written with positivistic and deductive scientific approach because it begins with finding of relevant theory, then collect data which are considered as objective facts. Empirical findings are combined with the theory to answer on our research questions. The quantitative and qualitative methods were applied, due to the fact that we obtained numerical data from financial department of GD to do ABC analysis and qualitative data through interviews and observations of GDs warehouses, to meet present situation between GD and SSC. Both primary and secondary sources were used for collecting empirical data by using scientific literature, interviews, and questionnaires. We used tables, flowcharts and diagrams for mapping the material and information flows between GD and SSC as well as ABC analysis presentation.  Scientific credibility of this thesis was assured through using of multiple sources of evidence, and also interviews and observations were followed and data adjusted by four people (group members).

Conclusions:

Three research questions were answered during this thesis. All of them have close relation to each other, and undertake existing problems in GD. The first question is concerning mapping of the material and information flows between GDs internal warehouse and rented one (SSC) which helped to identify the treatment areas in the mapped processes, and provide suggestions for future improvement. The second question is regarding location of SKUs of GD with the help of ABC analysis and ABC/ XYZ classification. The third question analyzes possibility of building new tent near to the GDs internal warehouse based on financial and operating criteria. Our analysis could be useful basis for future decision making of GD.

Suggestions for future research:

Regarding to the future research a lot of areas could be assessed. The layout of the GD facilities demands more attention. Based on identified treatment areas, deeper investigation on storage system of GDs internal warehouse and tent that GD already has outside the plant, has to be carried out.

 

Another significant area of the study is to continue to do ABC analysis of the SKUs, not only in the rented (SSC) warehouse, but also for entire GDs SKUs. This analysis will provide them an opportunity to organise the right location of their SKUs on the right place more efficiently.

 

Further research can also be done in the area of warehouse management. If GD finally decides to build a new tent close to the production line, new investments have to be analyzed deeper, for instance: returns from investments efficient utilisation of spaces, future possible expenses, warehousing costs and service level in future tent. On the basis of those analyses, GD can forecast more precisely the possibility of building new private warehouse.

Abstract:
Estimating parameters is the problem of finding their values from measurements and modelling. Parameters describe properties of a system; material, for instance, are defined by mechanical, electrical, and chemical parameters. Fisher information is an information measure, giving information about how changes in the parameter effect the estimation. The Fisher information includes the physical model of the problem and the statistical model of noise. The Cramér-Rao bound is the inverse of the Fisher information and gives the best possible variance for any unbiased estimator. This thesis considers aspects of sensitivity analysis in two applied material parameter estimation problems. Sensitivity analysis with the Fisher information and the Cramér-Rao bound is used as a tool for evaluation of measurement feasibilities, comparison of measurement set-ups, and as a quantitative measure of the trade-off between accuracy and resolution in inverse imaging. The first application is with estimation of the wood grain angle parameter in trees and logs. The grain angle is the angle between the direction of the wood fibres and the direction of growth; a large grain angle strongly correlates to twist in sawn timber. In the thesis, measurements with microwaves are argued as a fast and robust measurement technique and electromagnetic modelling is applied, exploiting the anisotropic properties of wood. Both two-dimensional and three-dimensional modelling is considered. Mathematical modelling is essential, lowering the complexity and speeding up the computations. According to a sensitivity analysis with the Cramér-Rao bound, estimation of the wood grain angle with microwaves is feasible. The second application is electrical impedance tomography, where the conductivity of an object is estimated from surface measurements. Electrical impedance tomography has applications in, for example, medical imaging, geological surveillance, and wood evaluation. Different configurations and noise models are evaluated with sensitivity analysis for a two-dimensional electrical impedance tomography problem. The relation between the accuracy and resolution is also analysed using the Fisher information. To conclude, sensitivity analysis is employed in this thesis, as a method to enhance material parameter estimation. The sensitivity analysis methods are general and applicable also on other parameter estimation problems.
Estimering av parametrar är att finna deras värde utifrån mätningar och modellering. Parametrar beskriver egenskaper hos system och till exempel material kan definieras med mekaniska, elektriska och kemiska parametrar. Fisherinformation är ett informationsmått som ger information om hur ändringar i en parameter påverkar estimeringen. Fisherinformationen ges av en fysikalisk modell av problemet och en statistisk modell av mätbruset. Cramér-Rao-gränsen är inversen av Fisherinformationen och ger den bästa möjliga variansen för alla väntevärdesriktiga estimatorer.Den här avhandlingen behandlar aspekter av känslighetsanalys i två tillämpade estimeringsproblem för materialparametrar. Känslighetsanalys med Fisherinformation och Cramér-Rao-gränsen används som ett redskap för utvärdering av möjligheten att mäta och för jämförelser av mätuppställningar, samt som ett kvantitativt mått på avvägningen mellan noggrannhet och upplösning för inversa bilder. Den första tillämpningen är estimering av fibervinkeln hos träd och stockar. Fibervinkeln är vinkeln mellan växtriktningen och riktningen hos träfibern och en stor fibervinkel är relaterad till problem med formstabilitet i färdiga brädor. Mikrovågsmätningar av fibervinkeln presenteras som en snabb och robust mätteknik. I avhandlingen beskrivs två- och tredimensionella elektromagnetiska modeller som utnyttjar anisotropin hos trä. Eftersom matematisk modellering minskar komplexiteten och beräkningstiden är det en viktig del i estimeringen. Enligt känslighetsanalys med Cramér-Rao-gränsen är estimering av fibervinkeln hos trä möjlig. Den andra tillämpningen är elektrisk impedanstomografi, där ledningsförmågan hos objekt bestäms genom mätningar på ytan. Elektrisk impedanstomografi har tillämpningar inom till exempel medicinska bilder, geologisk övervakning och trämätningar. Olika mätkonfigurationer och brusmodeller utvärderas med känslighetsanalys för ett tvådimensionellt exempel på elektrisk impedanstomografi. Relationen mellan noggrannhet och upplösning analyseras med Fisher information. För att sammanfatta beskrivs känslighetsanalys som en metod för att förbättra estimeringen av materialparametrar. Metoderna för känslighetsanalys är generella och kan tillämpas också på andra estimeringsproblem för parametrar.

Abstract:
My dissertation focuses on (i) the development of new analysis tools and methodologies for analyzing X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) data, and (ii) the comprehensive characterization of materials (nanodiamonds) using a multi-instrument approach. Chapter 1 contains (i) a discussion of the two techniques I focused on most in my work: XPS and ToF-SIMS, (ii) a discussion of the common chemometrics techniques used to analyze data from these methods, and (iii) the advantages/rationale behind the multi-instrument characterization of materials. Chapter 2 describes various good practices for obtaining reasonable peak fits in XPS, which can also be applied to peak fitting data from different techniques. To address the issue of user subjectivity/bias in XPS peak fitting, I introduce two less biased mathematical functions for characterizing XPS narrow scans, namely the equivalent width (EW) and the autocorrelation width (AW). These functions are discussed in Chapters 3 and 4. In Chapter 5, I then introduce uniqueness plots as simple and straightforward graphical tools for assessing the quality of XPS peak fits and for determining whether fit parameters are correlated. This tool is extensively used in spectroscopic ellipsometry, and the mathematics behind it is known in XPS. However, to the best of my knowledge, this graphical tool has never been applied to XPS. ToF-SIMS data analysis is somewhat challenging due to the enormous amounts of data that are collected, and also the matrix effect in SIMS. This amount of information is significantly increased when depth profiles are performed on samples. Chapter 6 discusses a new chemometrics tool that I introduce for analysis of complex data sets, with emphasis on XPS and ToF-SIMS depth profiling data. The new approach is called the Information Content (IC) or entropy, which is adapted from Claude Shannon's work on Information Theory. Chapter 7 then contains a presentation of the comprehensive characterization of five nanodiamond samples used to manufacture particles for liquid chromatography. The advantages of a multi-instrument approach for material characterization and the lack of comprehensive material characterization in the literature are emphasized. To the best of my knowledge this is the most comprehensive characterization of nanodiamonds that has been reported in the literature. Chapter 8 presents conclusions of my work and future work. This thesis also contains six appendices. Appendix 1 contains an article from a scientific magazine that I wrote to highlight the importance and applications of the EW and AW to characterize XPS narrow scans. Appendices 2-5 are application notes I wrote on separations I performed on a nanodiamond based HPLC column. Finally, Appendix 6 describes the ToF-SIMS analysis of the tungsten species in the nanodiamond samples characterized in Chapter 7.

Abstract:
In today’s fierce competitive global markets, customers are demanding adjustable lot sizes, shorter lead times, higher quality and flexibility; in short, they want it all. In order to stay competitive in the market, companies need to attain both customer satisfaction and cost reduction in production operations. Material Handling Systems (MHS) is the place to accomplish this goal, since they have a direct impact on production. Therefore, the aim of this study was to design an in-house MHS that could be efficient for the production it serves. With this intention, a case-study has been conducted in Bosch Rexroth Japan. During the study, the information gathered through various sources; interviews, observations and measurements. Further, the gathered data is evaluated according to main pillars of the theoretical framework, which includes design principles and physical elements, information and software, human and management. By analyzing the findings from literature review and empirical study, first problems and challenges related to MHSs are identified. Thereafter, possible features that the system should posses are elicited and a design is built out of the selected features. To conclude, the results show that the success is not solely depending on system’s physical attributes; on the contrary, it is more related to rapid and accurate information sharing within the system. Another vital element is the interaction between system and the people, who are utilizing and operating the system. In general terms, the research took MHS design problems from one-dimensional equipment selection processes and enriches them by adding information sharing, human and management angles to design steps.

Abstract:
This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. The aim of this project is to identify the elemental content of an incinerated ash sample, and to recommend a proper identification method when using XRD. Here, we test two ash samples (raw ash without any treatment and ash that has been stabilized by washing) using the software DIFFRAC.EVA that is integrated into Bruker’s diffractometer D2Phaser to match different diffraction patterns to identify the contents of the ash sample. Finally concluding the results XRF is more suitable than XRD for ash surveil-lance.

Abstract:
IT is a well-integrated function within most companies and its importance grows bigger by the day. With new solutions and concepts being introduced continuously it is important to be aware of the ever-changing possibilities found within IT. One of these changes is the concept of Industrie 4.0 which poses as a revolutionary way to do business by connecting the real world with the virtual one to a greater extent than what is done today. Research has shown that there are many possible benefits of implementing Industrie 4.0 and also Smart Factory, such as improved inventory control and faster reaction time. Since these concepts are quite new, no real definition exists and the congruence between the academic and business world is not always at the same level, and therefore the first steps are not yet defined. Therefore, this study tried to reduce the gap between these two worlds by offering concrete recommendations of what needs to be done to be able to apply Industrie 4.0 in the real world at Scania CV AB and Scania IT. Scania CV AB posed as a case company to find out where to start on the road to become smart. Currently there are many functions using the services of Scania IT, but exactly how the systems are used is not known by Scania IT. To be able to provide the necessary services for the various functions of Scania CV AB and start the road of becoming smart, Scania IT needs to know how the systems are used and what information that is currently missing. A formulated strategy of Scania, as a whole, is to be able to collect and analyse information in order to have a more Intuitive Presence and Predictable Future, two words meaning that more proactive work can be conducted and more autonomous decisions can be made. To be able to fulfil this vision, knowledge about the needed information must be acquired by Scania IT. With focus on the information connected to the material flow before the material reaches the assembly lines found at Scania CV AB the purpose of this study was to identify and analyse information and actions needed in the material flow from a user perspective, to become Intuitive and Predictable as part of the concept Industrie 4.0. A set of research objectives were formulated as a guide for the study. By first identifying, with the help of the first research objective, the information input and output for the functions at Scania CV AB connected to the material flow, with a base in the functions planning material, it was identified that at different production sites different standards of working exist, but also differences in the IT usage and system configurations was found.  The second research objective focused on what information should be available for production and material planning according to a literature review and this was later compared with the findings at Scania, which composed the third research objective. As it turned out, Scania uses the correct set of basic information such as forecasting, production plan, and calculations of gross demand, along with information regarding costs, lead times, and inventory. However, how to use the information is not standardized and the users of the IT systems perceived the information as hard to find and difficult to interpret. The fourth research objective focused on the concept of Industrie 4.0 and Smart Factories by studying literature, an external company and the ideas that Scania CV AB have, to see what must be done before a Digital Factory can be created. The recommendations for Scania IT were based on the result on the analyses and they can be summarized by the need of further standardization of information and information usage to be able to start the road of becoming Smart and take one step closer to the concepts of Smart Factory and Industrie 4.0.

Abstract:

The aim of this master's thesis is to present an introduction to semiological analysis of web based material, which is a hypothesis that combines the theoretical framework of classical Saussurean semiology, visual social semiotics as was developed by Günther Kress and Theo van Leeuwen, and Roland Barthes's notion of 'Myths'. Furthermore, a new tool called 'pseudo-signifier', constructed solely for the thesis, is also used in conjunction with the semiological analysis. The hypothesis is tested in a case study involving the web portal of a Swedish commune, Gothenburg (goteborg.se). A complete semiological analysis is performed on the case. The case study revealed numerous findings of interest, among others that images and texts on the web portal were sometimes used in a contradicting manner, and often in a way that symbollically excluded citizens from the portal, a fact which could be uncovered when studying underlying myths that permeated the web portal. The pseudo-signifiers combined with the notion of the Barthean myth proved to be an important tool in order to analyze images and texts on web material, to show how images and texts are to be seen together, not one by one by themselves. An attempt was also made to make the pseudo-signifiers a mean to provide assistance to the creators of the web portal, in order to make the portal more user- and information friendly.

Denna rapport tar upp teorier och metoder kring användbarhet i skapandet av en Flash-applikation. Rapporten beskriver steg för steg i skapandeprocessen, hela vägen från att ta fram behov och användningsområde till att skapa innehållet och slutligen en utförlig redogörelse för hur applikationen sammansätts. Metoderna som använts är huvudsakligen ITK (Identity Tool Kit) och scenarier enligt Alan Cooper. Vidare har metoder för hopsättning och visualisering av applikationen använts med stöd av Nielsen och Raskins användbarhetsprinciper. Resultatet visar att för att använda ITK i syfte att kartlägga en verksamhet, kräver detta en stor förståelse och modifikation av denna. Det visar också att Alan Coopers teorier om scenarier inte heller kommer till sin rätt utan en utförlig analys av användarna i denna. Resultatet visar även att med hjälp av programvarorna 3D studio Max och Flash kan interaktivt innehåll för produktvisualisering på nätet skapas med goda resultat.


This report addresses the theories and methods of usability in creating a Flash application. The report describes step by step in the creative process, all the way from the development needs and use to create content and finally a detailed explanation of how the application assemblies. The methods used are mainly ITK (Identity Tool Kit) and scenarios according to Alan Cooper. Furthermore, methods of assembly and visualization of application used with the support of Nielsen and Raskin usability principles. The result shows that the use of ITK in order to identify an activity, this requires a great understanding and modification of this. It also shows that Alan Cooper's theories about the scenarios do not come into its own, without a detailed analysis of the users thereof. The results also show that using the software 3D Studio Max and Flash for interactive content for product visualization on the web is created with good results.

The purpose of this study is to create a model which will help when working with improvements. The model is based on a Maintenance Function Deployment which helps to highlight the areas within a company that should be improved and focused on in order to make the organization more effective. The model consists of seven steps which in different ways identifies and analyzes the organization and the production process. In the model not only technical aspects are addressed, but aspects related to human resources as well as corporate culture. With two different case companies, manufacturing the same product, this study is investigating how to improve one of them, with the inspiration of the other.   In this study it was highlighted how important the material and information handling systems are and how they would affect the company to the better if they were implemented. With different tools the entire production process and its different steps were analyzed in order to prove the effect of implementing such a change and finally a suggestion for the company is recommended which evidently would give results. The results concerns both smaller changes within the production flow and bigger changes which are more expensive and would mean a lot of more work, although with a greater result.

Abstract:
This thesis evaluates and compares the retrieval effectiveness of the two search engines Google Scholar and Scirus, which both specialises in indexing scholarly material on the web as well as journal articles. Thirty search queries are used and the first twenty retrieved documents for each query are examined for topical relevance and scholarly content. The search queries are based on legitimate information needs taken from a scientific questionbox on the web. Queries are expressed with advanced search operators and are the same for both search engines. Precise relevance criteria are set up and a binary scale is used when judging. Inactive, duplicate, and mirror links are all considered non-relevant, as well as documents judged as non-scholarly. Two methods of measuring precision are used: average precision at each DCV for all search queries, and average precision at each DCV for each search query; which both credit ranking of relevant documents. As for scholarly content, both relevant and non-relevant documents are judged, and results are expressed in per cent. When judging scholarly content, guiding principles are being followed. There is not a great difference in results between the two search engines, although Google Scholar provides slightly higher results for all precision measures as well as being the best in retrieving scholarly material. However, Scirus is the better at retrieving relevant documents at DCV = 1 and DCV = 2, as showed by average precision at each DCV for all search queries.

Abstract:
Det här arbetet har utförts hos Sandvik SMT OFP och handlar om vidareutvecklingen av en prototypenhet som kombinerar EC- och UT-prober. Båda dessa mättekniker tillhör den överhängande gruppen som kallas oförstörande provning och är menade att felsöka material utan att inverka negativt på dem. Prototypen är tänkt att användas för att mäta skikttjocklek på compound-rör. Dessa rör består av två skikt varav ett är feritiskt kolstål, och det andra rostfritt stål. Det yttre, icke-feritiska skiktets tjocklek mäts med hjälp av EC-proben. Dettagörs genom att kalibrera proben mot ett testobjekt med kända tjocklekar mellan två av vilka en linjärisering utförs. Därefter placeras proben mot mätobjektet varpå mätningen jämförs mot linjäriseringen. Den totala tjockleken mäts med UT-proben och med dessa två mätningar blir även tjockleken av det feritiska skiktet känt. I tidigare system har EC- och UT-prober suttit separata och därmed har det funnits en risk att mätpunkterna för de två proberna har blivit osynkroniserade. Förhoppningen är att den kombinerade proben ska kunna utföra de två mätningarna samtidigt, på samma punkt för att minimera denna typ av fel. Arbetet visar att isolering av kopplingspunkter på proben kan räcka för att stabilisera EC-mätningar i vatten. Det förefaller rimligt att med mer arbete kunna driftsätta en kombinerad EC- och UT-prob samt att ett nytt instrument för hantering av EC-delen skall kunna designas.
This thesis work was conducted at Sandvik SMT OFP and deals with the further development of a prototype unit that combines EC- and UT-probes. Both of these probes associated measurement techniques belong to the greater group known as non-destructive testing and are intended to detect flaws in materials without negatively affecting them. The prototype is intended to to be used for measuring the thickness of compound tubes. These tubes consist of two layers, one of which is made of ferrous carbon steel, and the other of stainless steel. The outer, non-ferrous layers thickness will be measured with the EC-probe. This is accomplished through calibration with a well defined test object with sections of known thicknesses, between two of which a linearization is made. After calibration, the probe is placed against the object that is to be measured and the result from the EC-probe is compared to the linearization. The total thickness is measured by the UT-probe and with these two measurements the thickness of the ferrouslayer is indirectly known aswell. In earlier systems EC- and UT-probes have been separated and thus there were issues with desynchronization of measurements between the two probes.The combined probe is expected to make both types of measurements simultainiously, at the same point in order to reduce the risk of this type of error. This project shows that isolation of connections between probe and wire could suffice to stabilize EC-measurements in water. It appears reasonable to believe that with more work, Sandvik SMT OFP could use a combined EC- and UT-probe in production, and that a new instrument for handling the EC-measurements could be designed.
